Specification of Letters IPatent.

Patented J une 25, 1912.

T 0 all 'whom t may concern Be it known that I, CHARLES A. Moons, a citizen of the l United States, residing at St. Paul, in the county of Ramsey and State of Minnesota, have invented a -new and useful Improvement in Refrigerator-Cars, of which the following is a specification.

`My invention relates to improvements in refrigerator cars which are cooled, heated and ventilated.

The primary object attained by this invention is the maintenance of a suiiiciently low temperature within they car when the outside atmosphere is, warm and of a temperature above freezing when the outside atmosphere is below.

.Further objects are to provide an efficient and eective system of internal air circulation and the largest surface for cooling or heating the atmosphere. in the smallest pos- 'sible space whereby the dimensions of the inclosure are least encroached upon by the room taken up by the apparatus.

Depending in part upon these requirements I provide in the car inclosure an ice bunker between the ends of the car and eX- tending from the floor to the roof thereof and means for raising the temperature of the air within the car and circulating said air in an eiiective manner.`

My invention further consists of the features, details and combinations of parts v hereinafter described and claimed.

In the accompanying drawings, forming part of this specification, Figure 1 1s a longitudinal sectional View of a portion of a refrigerator car illustrating my invention; Fig. 2 is a plan view partly in sectlon taken on 4the line A-A of Fig. l; Flg. 3 is a cross section of Fig. 1 taken on the line B-B; Fig. 4 is another cross sectional view of Fig. 1 taken on the line C-C; Fig. 5 1s a longitudinalsectional view of a portion. of a refrigerator car illustrating an alternative construction of my invention, and F1g. 6 1s a cross sectional view of Fig. 5 taken on the line D-D and showing a portion of the ice bunker broken away. The oar body proper, that is, its sides E, roof F, ends G and Hoor I-I is made in any desired form and I do not limit the application of my particular improvements to the special and general construction shown in the drawings.l The sides, Hooring, ends and roof of the car are preferably made double, treble, or quadruple, with any desired number of dead air spaces I, between the separate portions of the walls, which air spaces may, if desired, be filled with any suitable material which will serve to insulate the interior of the car. The inner spaces J however, are not filled with any material and are adapted to conduct. the hot and cold air issuin from the heating chamber K and ice bun (er L into the car.

The ice bunker L isy located substantially A midway between the ends of the car and eX- tends from the floor to the roof. This bunker has an'overhead tray 2 extending across, immediately below and spaced from the roof of the car, the tray being supported by transverse and longitudinal I-beams 3. The ends of the transverse I-beams are set in the sides of the car and the intersections' of all of the beams are connected by means of angle bolts 4f which are secured thereto by rivets 5. vFloor planks 6 are supported by the I-beams, and angle slats 7 are placed above the floor planks upon space bars 8. The angle irons are suiioiently spaced apart so as to permit water todrip from the ice in the bunker between the slats and upon the'fioor of the tray from where it is conducted below the car by means of drip pipes 9. A section 10 of the tray is made removable for the purposes to be hereinafter described. The ends of the overhead ice thecar leaving a passageway for the loading and unloading of the car through the doorway 13. The ends of the lower bunker are constructed by vertical posts 14: having wire meshing 15 fastened outside and transverse downwardly and inwardly inclined slats 16 which are spaced apart and fastened between said posts. Near the bottom of the` lower ice bunker is a horizontal grating 17 which supports the ice and allows air to 110 circulate downwardly through the bunker and the water to drip from the ice below it. Spaced below the grating so that air is free to circulate downwardly through the lower ice bunker and into the provision chamber is a downwardly and inwardly inclined drip pan 18 which catches the water dripping from the ice and conducts it from the car through a downwardly directed vent pipe 19.

In the roof of the car and immediately above the upper ice bunker M are hatchways 20 through which ice is adapted to be placed in the lower and upper ice bunkers, it being understood that when the lower lce bunker is iced the'section 10 of the tray 1s removed through oneof the hatchways or placed at one side of the upper ice bunker. By this means the disposition of the ice in the ice bunker is arranged so that either part or all of the ice bunker can be used and when it is desired to keep the ice near the roof of the car and maintain only part of the bunker in operation, the section 1 0 of the tray can be inserted in place. The lower ice bunker as shown is adapted to expose a larger area of ice to the atmosphere in the provision chamber than the upper section.

n 1ce bunker.

The` -Ventilating passageway J' connects with the top' of' the upper ice bunker and leads into the provision chamber by the openings 21. In this manner the air in all portions of the car is circulated through the The lower end of the air ventlating passageway J connects with the upper portion of the heating chamber K which 1s supported below the floor and substantiallymidway between the ends of the car. This heating chamber is provided with a heater' 22 and a door 23 by'which access is had into the heating chamber for therpurpose of operating the heater.

The heater is of ordinary construction and the heating chamber has air inlets 24 through' which fresh air passes into the heater and up into the provision chamber of the car and the ice bunker. The roof above the upper ice bunker has an air vent 25 leading to the outer atmosphere for the purpose of Ventilating` the car.

In the alternative construction, the lower ice bunker N extends across the provision chamber a-nd connects between the sides of the' car and is particularly adapted for use with a car having doorways 26 near each of its endsv instead of midway between ends as 'shown in the preferred construction. The length of the ice bunker is considerably less than the length used in the preferred construction, otherwise the parts are of' substantially similar construction except that the slats 16 and wire meshing l5 are used in the ends instead of the side walls -of the bunker.

In operation, when it is desired to cool the atmosphere in the car ice is placed in the lower and upper bunkers through the hatchways in the roof which are afterward sealed. The' cold air from the bunkers passes into the car through the open-work walls of said bunker and the air conducting passageway J. When it is desired to heat the car, the heater 22 is operated. Air then freely circulates around theheaterfrom the passageways 24 and up into the car through the conducting passageway J and port openings 21. It also enters the car through the ice bunker. In this manner warm or cold air freely circulates through the car when the heater or refrigerator is in operation.

When desired, the inlets 24 may be provided with valves 28 so that the admission of fresh and cold air into the car can be controlled. To increase the ventilation of the car the ventilator 25 can be opened when the heater, refrigerator, or both arein or out of operation.

In accordance with the patent statutes, I have described the principle of operation of my invention, together with the apparatus which I now consider to represent the best embodiment thereof, but I desire to have it understood that the apparatus shown is only illustrative and that the invention can be carried out byother means and applied to uses other than those above set forth, within the scope of the following claims.

Having described my invention, what I claim as new and desire to protect by Letters Patent, iszl. A refrigerator car, comprising, in combination, a car body having a roof substantially straight throughout the length of the car and a provision chamber extending entirely from end toend thereof, anice bunker immediately below .the roof and having ends remote from the ends of the car opening into the top of the provision chamber for the circulation of air, said bunker having a longitudinal upper portion and an auxiliary lower portion extending from the Hoor of the provision chamber to the ioor of the upper portion of said bunker, an ice grate in the lower portion of said bunker, a hatchu way entering said bunker through the roof of the car and a removable tray section in the ioor of said bunker between the upper and lower portions of said bunker, whereby ing directly into the top of the provision 13,9/

chamber for .the free circulation of air and having an apertured floor, a removable tray section tted to the aperture in said door,

and a 'second ice bunker below said floor and in said provision chamber adapted to receive ice from said rst bunker in the open position of said tray.

3. A refrigerator car, comprising, in combination, a car body-having a roof substantially straight throughout its length and a provision chamber extending entirely from end to end thereof, an ice bunker immediately below Vthe roof of the car having both-ends remote from the ends of the car and extending the entire inside width of the car body and provided with upright ends opening directly into the top of the provision chamber for the free circulation of air, a hatchway in the roof of the car over said ice bunker, and a second ice bunker having a median position in said provision chamber CHARLES A.
